GIVEN INFO
LP gas burns according to the following exothermic
reaction:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)
ΔH∘rxn= −2044kJ
What mass of LP gas is necessary to heat 1.4 L of water from room temperature (25.0 C) to boiling (100.0 C)? Assume that during heating, 16% of the heat emitted by the LP gas combustion goes to heat the water. The rest is lost as heat to the surroundings.
